1. A. truncata F. & M. Columbine. Glabrous, 2 to 3J ft. high; 

 leaves biternate, the leaflets roundish in outline, broadly cuneate at 

 base, at summit incised, the segments lobed or crenately toothed; 

 petioles long, those of the radical leaves 1 ft. long; flowers scarlet, 

 tinged with yellow,, pendulous in anthesis; spurs, therefore, erect, f in! 

 long, somewhat exceeding in length the widely spreading sepals, and 

 truncate at the orifice, the blade being almost none; follicles nearly 

 1 in. long, conspicuously, veined, the long styles persistent. 



Moist, shaded places in the lower hills, or at middle altitudes in the 

 mountains, almost throughout California; not in the inner Coast 

 Eanges. May-June. 



4. DELPHINIUM L. Larkspur. 

 Herbs, ours perennial, with palmately divided leaves. Flowers in 

 terminal racemes. Sepals 5, irregular, the upper one produced into a 

 spur at the base. Petals 4, in pairs, with small spreading usually 

 oblique blade on a claw of about equal length, the upper developed 

 backward into nectary-bearing spurs and concealed within the spur of 

 the calyx. Pistils in ours 3, seldom more, becoming many-seeded 

 follicles. (Greek delphinion, larkspur, derived from delphin, the 

 flowers of some species resembling the classical figures of the dolphin.) 



Flowers blue, white, pink or lavender-color. 

 Roots woody-fibrous or fusiform-thickened. 

 Lower leaves 4 to 7 in. in diameter; flowers wliitish; sepals externally 



villous all over \. D. Califomicum. 



Ijeaves mostly 1 to 3 in. in diameter; sepals finely pubescent or nearly 

 glabrous, not villous. 

 Racemes commonly rather short and few-flowered; pedicels spreading; 



sepals 7 to 10 lines long 2. I), vanegatum. 



Raceme commonly elongated and many-flowered; pedicels erect; sepals 



4 to 7 lines long .... . 3. Z>. hesperium. 



Root a more or less globose tuber.

 Follicles j| in. or more long, widely spreading; flowers few and large. .

 Flowers red . . . .6.X). nudicaule. 



1. D. Californicum T. & G. Coast Lakkspue. Stout, 2J to 7 

 ft. high, sparsely pubescent, many-leaved; .leaves very large, 4 to 6 

 in. broad, 2 to 4 in. long, deeply parted into 3 to 5 segments; segments 

 incised, sinuses of the primary divisions mostly closed in the lower 

 leaves, open in the upper; racemes dense, J to IJ ft. long; pedicels 4 

 to 7 lines long, or the lowest somewhat more; bractlets very long and 

 slender; flowers rather densely pilose-pubescent, white or whitish or 

 somewhat purplish inside, never fully expanded; upper petals entire 

 or very slightly emarginate with a woolly tuft at apex on the inside; 

 lower pairs bifid, woolly on the outside; spur mostly longer than the 

 sepals; follicles oblong, turgid, hardly if at all diverging. 



Throughout our region toward the coast, but not common, flower-
